    some of this is true, some false, but all of it is pretty irrelevant to the benefits of free form optics. Sharpstick's original post and Robert's analysis are correct.

    Interesting thread from the dead.

    To what degree can best fit base curves be "ignored" in SVFF design? Could you create an "inverse" lens with convex side toward the eye and concave side facing forwards with minimal distortion?
